Mesothelial cyst of the round ligament

Mesothelial cyst of the round ligament is a rare finding in females, with only a few cases reported so far. A case of a 25 year old female patient presenting with a palpable mass in her right inguinal region is presented. The preoperative investigation through ultrasound (U/S), computed tomography (CT) and magnetic resonance imaging (MRI) revealed the presence of an intraabdominal cystic lobular mass in the inguinal canal, in contact with the femoral vessels. The mass was excised and the diagnosis of a benign mesothelial cyst was made through pathological examination. Even though it is a rare condition, it is advisable that clinicians consider in the differential diagnosis when evaluating a non-reducible mass in the inguinal region of a female patient.

Adverse cardiovascular outcomes in relation to suboptimal antithrombotic therapy use in patients undergoing peripheral artery disease angioplasty: lost opportunities?

INTRODUCTION

Current guidelines recommend antithrombotic therapy with either aspirin or clopidogrel for all patients with peripheral arterial disease (PAD). Nevertheless, cardiovascular comorbidities and perceived bleeding risk complicate antithrombotic management of PAD patients. We studied the proportion of patients receiving optimal (guideline-recommended) antithrombotic therapy, and second, assessed the impact of suboptimal antithrombotic therapy use to long-term outcomes of PAD patients.

METHODS

We performed a single centre retrospective analysis of patients with significant PAD, requiring percutaneous intervention. All patients coded as undergoing peripheral artery percutaneous transluminal angioplasty (PTA) between January 2007 and December 2011 were reviewed. Antithrombotic medication on discharge postprocedure was recorded.

RESULTS

Across the study period, 473 patients were coded as having received a PTA, but yet only 336 (71%) had data available for review: 218 (35.2%) male, mean age 73 ± 11 years. Of the whole cohort, 236 (70.2%) were discharged on optimal (guideline-recommended) antithrombotic therapy, 30 (8.9%) were considered 'overtreated' and 70 (20.8%) were undertreated. On multivariate analysis, patients with heart failure were more likely to be undertreated (OR 2.38, 95% CI: 1.15-5.00, p = 0.02) while patient with coronary artery disease were more likely to be overtreated (OR 4.00, 95% CI: 1.61-10.00, p = 0.03). Undertreated patients had an increased risk for all-cause mortality [hazard ratio (HR) 2.96, 95% CI 1.81-4.82: p = 0.00001] and cardiovascular mortality (HR 3.16, 95% CI: 1.49-6.68, p = 0.003).

CONCLUSION

In this single centre cohort of patients undergoing PTA, suboptimal antithrombotic therapy was not uncommon and had a major impact on long-term outcomes, resulting in increased all cause and cardiovascular mortality.

Atrial fibrillation as a risk factor for cognitive impairment: a semi-systematic review

It is unclear if atrial fibrillation (AF) is an independent risk factor for cognitive impairment. This review evaluates the available evidence and provides an overview of the association between AF and cognitive function. Electronic database searches, January 1990 to December 2012, identified 271 studies comparing the incidence of cognitive impairment and/or dementia in patients with/without AF. Cognitive function was diagnosed by a physician using the mini-mental state examination (MMSE) or other established diagnostic criteria. Studies with <20 participants and without direct comparison to controls in sinus rhythm were excluded. There were no restrictions on the basis of age, language or study design. Full texts of 11 studies were obtained. Eight studies (three cross-sectional, two case-control and three prospective cohorts) reported an association between cognitive decline and AF. Among cross-sectional studies, patients with AF had a 1.7 (95% CI 1.2-2.5) to 3.3 (95% CI 1.6-6.5) greater risk of cognitive impairment, and a 2.3-fold (95% CI 1.4-3.7) increased risk of dementia, compared to patients in sinus rhythm. There was marked heterogeneity in the design, size and quality of studies and reporting of the data which precluded formal meta-analysis. Eight studies reported an association between AF and cognitive impairment and/or dementia, but the magnitude of risk varied. Further large-scale prospective studies are needed to establish whether AF is a risk factor for cognitive decline, utilizing objective measures of cognitive function and neuropsychological testing, and to investigate the potential benefit of anticoagulation on reducing cognitive impairment and development of dementia.

The impact of atherosclerotic vascular disease in predicting a stroke, thromboembolism and mortality in atrial fibrillation patients: a systematic review

BACKGROUND

Atrial fibrillation (AF) is commonly associated with vascular disease. Although atherosclerotic vascular disease (for example, defined as a myocardial infarction (MI), complex aortic plaque and peripheral arterial disease) has been proposed as a risk factor for a stroke, the co-existence of the two diseases increases the risk of future cardiovascular events. The objective of this study was to conduct a systematic review to assess the impact of atherosclerotic vascular disease on the primary end-point of a stroke, thromboembolism or mortality, in patients with AF.

METHODS

Literature searches were performed electronically, to identify studies published between January 1990and July 2012 examining stroke and thromboembolism in relation to AF and atherosclerotic vascular disease. Nineteen articles satisfied the pre-inclusion criteria. The bibliographies were subsequently screened to retrieve further relevant studies for this review.

RESULTS

Peripheral arterial disease significantly increased the stroke risk in all 10 observational studies, within a reported risk range of 1.3- to 2.5-fold. Complex aortic plaque on the descending aorta, as identified by trans-oesophageal echocardiography, was also a significant risk factor. Although a prior myocardial infarction (MI) was validated as a significant predictor of the primary end-point amongst five of the six studies, there was a degree of heterogeneity, owing to the marked difference in population sizes and the use of antithrombotic regimens between studies.

CONCLUSION

Atherosclerotic vascular disease (e.g. peripheral arterial disease, complex aortic plaque and prior MI) are significant predictors of a stroke, thromboembolism and mortality in subjects with AF.

Disclosure of cancer diagnosis: the Greek experience

PURPOSE

To analyze the attitude of Greek health professionals towards truth disclosure and factors that may influence it.

METHODS

Through a self-completed questionnaire, we studied the attitudes over the initial disclosure of cancer diagnosis to cancer patients of 132 doctors and 123 nurses, partly involved in cancer patients' care, in 5 general hospitals of Crete, Greece.

RESULTS

Eighty-nine percent of the participants considered information as patient's right and 88% as professional's ethical duty, 64% believed that the whole truth should be revealed, 90% avoided the word "cancer" in the communication and 39% disclosed cancer diagnosis at patient's direct asking. Respondents informed 1/10 of their new cancer patients, mainly due to perceived limited responsibility (23%), patient's low cognitive state (22%), fear of harming the patient (17%) and relatives' objection (15%). Sixteen percent of fellows acknowledged to themselves the responsibility to inform patients. Cooperation, compliance and arrangement of patient's personal issues were considered as benefits from accurate disclosure (88%, 83% and 75%, respectively), the latter more among doctors than nurses (p=0.01) and medical than surgical professionals (p=0.03). Thirty-six percent of the respondents considered the presence of a psychologist necessary during disclosure, nurses more than doctors (p<0.001).

CONCLUSION

Despite adequate theoretical background, Greek non-cancer specialists, doctors and nurses, initially inform accurately a small part of their cancer patients. Appropriate training programs for doctors and non-medical health professionals involved in cancer patients' management are required to upgrade professional-patient communication.

Immunophenotypic characterization of human monocyte subsets: possible implications for cardiovascular disease pathophysiology

OBJECTIVES

Monocytes include several subsets with different and sometimes divergent roles in immunity, atherogenesis and reparative processes.

OBJECTIVES

We aimed to perform detailed immunophenotypic and functional characterization of human monocyte subsets.

PATIENTS/METHODS

Analysis of surface markers of blood and bone marrow monocyte subsets and functional characterization of blood monocyte subsets in healthy volunteers was performed using flow cytometry.

RESULTS

In the present study, we show the presence of three subsets which could be unequivocally distinguished by surface expression of CD14, CD16 and CCR2 as CD14(+)CD16(-)CCR2(+) (Mon1), CD14(+)CD16(+)CCR2(+) (Mon2) and CD14(low)CD16(+)CCR2(-) (Mon3) subsets. In comparison with the classic Mon1, the Mon2 subset had the highest expression of Tie2, CXCR4, CD163, CD115, receptors to inter-cellular adhesion molecule-1 (ICAM-1), vascular endothelial growth factor (VEGF), and the highest surface levels of apolipoprotein B and ferritin. In contrast, Mon3 had maximal expression of VCAM-1 receptors and CD204. The Mon2 and Mon3 subsets had significantly lower activity of the NFκB pathway than Mon1. Mon1 and Mon2 had similar phagocytic activity, which was significantly higher compared with Mon3. All three subsets were present in bone marrow, although the relative proportion of Mon2 in bone marrow was about 2.5-fold higher compared with that seen in blood. Significant differences in cytokine production in response to endotoxin stimulation were observed between the three monocyte subsets.

CONCLUSION

Given their immunophenotypic similarity, the newly characterized Mon2 population may represent the previously reported pluripotent progenitor/pro-angiogenic monocytes.

Clinical burden of terminal phase in cancer patients

PURPOSE

Symptoms, palliative applications and terminal phase (TP) duration mainly constitute clinical burden of TP in cancer. The aim of this study was to describe palliative issues and determine factors that might influence the clinical burden during TP.

PATIENTS AND METHODS

We retrospectively studied 125 terminally ill cancer patients, of median age 70 years and ECOG performance status (PS) 4, at their TP entry, who died over a 3-year period, 90 (72%) in hospital (group 1) and 35 at home (group 2).

RESULTS

During TP, the 10 most prevalent symptoms were anorexia, pain, dyspnoea, cachexia, fever (infectious or not), constipation, ascites, agitation and vomiting. The 10 most frequent palliative applications were administration of i.v. fluids/drugs, oxygen and enemas administration, bladder catheter and central venous (CV) line care, transfusions, gastric, pleural and peritoneal fluid drainage, endoscopic or percutaneous biliary tract decompression, and radiotherapy. In total, TP represented 8% of the whole disease duration, causing 17% of admissions and 28% of hospital stay. Tumor complications and treatment toxicities caused death and shortened TP in 70% of the cases, more frequently in group 1 (p=0.027). Long disease active phase (AP) duration (from initial diagnosis of cancer to TP entry) predicted PS<4 at TP entry (p=0.008). Predictors of TP duration were AP duration (p=0.010), PS <4 (p=0.000) and number of clinical features (p=0.012).

CONCLUSION

TP represents a small percentage of patients' total disease duration, but it constitutes a considerable part of the entire hospital patients' in-stay and professional practice. PS at TP entry predicted TP duration. AP influenced PS at TP entry and predicted TP duration. AP is an easily measurable clinical parameter and may be considered as an additional prognostic factor of TP duration.

Hoarseness as imminent symptom of aortic aneurysm rupture (Ortner's syndrome)

Ortner's syndrome (cardiovocal syndrome) is the clinical entity of hoarseness due to left recurrent laryngeal nerve palsy caused by cardiovascular disease. We present a case of an 86-year-old woman with hoarseness as a prominent symptom due to a large painless aneurysm of the thoracic aorta, which soon ruptured. Cardiovocal syndrome can be a rare but an important and probably the only major clinical finding of a painless aortic rupture.

Distribution of HIV/AIDS protective SDF1, CCR5 and CCR2 gene variants within Cretan population

An interesting finding in the epidemiology of human immunodeficiency virus (HIV) infection is that certain mutations in genes coding for chemokine receptors and their ligands may confer resistance to HIV-1 infection and/or AIDS progression. The mutations most frequently studied are the CCR5-delta32, CCR2-64I and SDF1-3'A. We examined the frequency of the above polymorphisms within the Cretan population, evaluating their contribution to a protective genetic background against HIV infection and progression. Two hundred blood samples were recruited at random among prospective blood donors from Crete. Genotyping was initially performed by polymerase chain reaction (PCR) analysis. CCR2 and SDF-1 PCR-amplified genomic regions were further subjected to restriction fragment length polymorphism (RFLP) analysis for genotype determination. The CCR5-delta32 allele frequency among our study group was 3.25%, although no respective homozygous samples were detected. The screening for the CCR2-64I polymorphism yielded 39 heterozygous (19.5%) and 4 homozygous (2%) subjects, revealing a CCR2-64I allele frequency of 11.75%. Among our 200 PCR-RFLP analysed samples, 73 (36.5%) were found heterozygous and 23 (11.5%) homozygous for the SDF1-3'A mutant variant. The allele frequency of the above polymorphism reached 29.75%. The frequency of the CCR5-delta32 allele among our study population seems to be remarkably lower compared to previously reported frequencies in other Caucasian groups. However, the SDF1-3'A allele frequency shows significantly higher distribution profiles within our study group compared to those observed in other Caucasian-European populations. The indicated difference could be attributed to the increased homogeneity of our population, which is well balanced and dispersed over a small geographical area. Since this polymorphism is related with delayed progression from HIV infection to AIDS, it could be used for prognostic genotyping in HIV infected Cretan individuals.
